Sulfuric acid (H2SO4) is a strong, heavy acid with a
density of 1.84 g/cc and a marked tendency to
absorb moisture from the air, generating much heat.
Concentrated sulfuric acid (93-98%) is used in the
manufacture of fertilizers, explosives, dyes, and
petroleum products. Sulfuric acid is formed during the
Contact Process. The ContactProcess forms sulfur
trioxide (SO3) gas from sulfur dioxide (SO2) and oxygen
in a catalyst tower, and sulfuric acid is formed
when water is added. A mixture of H2SO4 and free
SO3 is equivalent to a sulfuric acid concentration of
over 100 percent. This mixture is called fuming sulfuric
acid or oleum.

Germany's ChancellorAngela Merkel said she has made the first contact with the head of the Social Democratic Party about forming a grand coalition government, but that any talks will have to wait for several days.
The Social Democrats are scheduled to hold a party convention on Friday, and will likely discuss participation in the government there.
Merkel's Union bloc scored its best result in 23 years on Sunday to put her on course for a third term, winning 41.5 percent of the vote and finishing only five seats short of an absolute majority in the lower house.
She now faces the delicate work of forming a coalition government.
Merkel's coalition partner, the pro-business Free Democrats, lost all their seats in Parliament after a much-criticised performance in Merkel's outgoing government.
Merkel and top party officials met on Monday to talk strategy about reaching out to the centre-left rivals they need to form a government.
She looks likely to end up leading either a "grand coalition" government with the centre-left Social Democrats of defeated challenger Peer Steinbrueck - reviving the alliance that ran Germany in her first term - or, less likely, with the environmentalist Greens.
Several weeks of difficult negotiations are expected, as both of the potential partners are likely to be wary of entering a coalition with the Christian Democratic Union (CDU).
Junior partners in the last two coalitions suffered disastrous defeats after four years of partnership with the CDU.

Contact mechanics is the study of the deformation of solids that touch each other at one or more points. The physical and mathematical formulation of the subject is built upon the mechanics of materials and continuum mechanics and focuses on computations involving elastic, viscoelastic, and plastic bodies in static or dynamic contact. Central aspects in contact mechanics are the pressures and adhesion acting perpendicular to the contacting bodies' surfaces (known as the normal direction) and the frictional stresses acting tangentially between the surfaces. This page focuses mainly on the normal direction, i.e. on frictionless contact mechanics. Frictional contact mechanics is discussed separately.
Contact mechanics is foundational to the field of mechanical engineering; it provides necessary information for the safe and energy efficient design of technical systems and for the study of tribology and indentation hardness. Principles of contacts mechanics can be applied in areas such as locomotive wheel-rail contact, coupling devices, braking systems, tires, bearings, combustion engines, mechanical linkages, gasket seals, metalworking, metal forming, ultrasonic welding, electrical contacts, and many others. Current challenges faced in the field may include stress analysis of contact and coupling members and the influence of lubrication and material design on friction and wear. Applications of contact mechanics further extend into the micro- and nanotechnological realm.

Learn how to use Microsoft Outlook to create contact groups so that you can send emails to a large number of people easily.
It is always better to create contact groups in outlook as it allows you to send emails to a large number of people easily. By creating groups you do not have to specify each and every email address specifically but can simply enter the contact group that consists of all email ids.
To understand how to do this, follow the tutorial below.
Step # 1 -- Select the "New Contact Group" icon
In outlook 2010 the "distribution list" is renamed to "contact group". This is the list that you will use to send out emails with Outlook to your contacts. It is easy to create contact groups once you have created the contacts. You will start by clicking the "contacts icon" in the "navigation pane". Then click on the "new contact group icon" at the top.
Step # 2 -- Enter the name
A new window will open the first thing you will do is to give the group a name, in this example "office staff". Once you have named the group, you would find it in your contacts. To make it appear right at the top, change the name by double clicking the group and in the name bar adding an "Underscore sign" before the name.
Step # 3 -- Add members
After you create contact groups in Outlook add contacts to it by double clicking on it and clicking on the "add members" icon. It will show you options from where you can add members to the group. In this example we will add members from the "outlook contacts". Once you select it, a window will appear showing you all the members. Add them by double clicking on the contact. After selecting the members click "ok" and a list of the selected members comes on the screen. From there, click "save and close".
You can at any point in time add a new member to the group or delete one by selecting it and clicking the "remove member" icon. Click "save and close" after you make changes.
Step # 4 -- Send email to group
There are four ways in which you can send emails in Outlook to a group. The first one is by right clicking on the group, going to "create" and selecting "E-mail". You will notice that the group name comes in the "To" line automatically. The second way to send an email is by opening the group, going to the communicate panel and clicking on the "E-mail icon". Another way to send an email is by going to the "folder list". The advantage of "folder list" is that you can see your contacts and mail box at the same time and drag the group in the inbox folder. The fourth and last way to send the email is simple you just have to click the "new Email" icon. A new email window will open. In the "To" bar type the first few letters of the contact.

Contact lens

A contact lens, or simply contact, is a thin lens placed directly on the surface of the eye. Contact lenses are considered medical devices and can be worn to correct vision, or for cosmetic or therapeutic reasons. In 2004, it was estimated that 125 million people (2%) use contact lenses worldwide, including 28 to 38 million in the United States. In 2010, worldwide contact lens market was estimated at $6.1 billion, while the U.S. soft lens market was estimated at $2.1 billion. Multiple scientists estimated that the global market would reach $11.7 billion by 2015.As of 2010, the average age of contact lens wearers globally was 31 years old, and two thirds of wearers were female.

People choose to wear contact lenses for many reasons. Aesthetics and cosmetics are often motivating factors for people who would like to avoid wearing glasses or would like to change the appearance of their eyes. Other people wear contacts for functional or optical reasons. When compared with spectacles, contact lenses typically provide better peripheral vision, and do not collect moisture such as rain, snow, condensation, or perspiration(extreme weather); this makes them ideal for sports and other outdoor activities. Contact lens wearers can also wear sunglasses, goggles, or other eyewear of their choice without having to fit them with prescription lenses or worry about compatibility with glasses. Additionally, there are conditions such as keratoconus and aniseikonia that are typically corrected better by contacts than by glasses.

Khan Academy

Khan Academy is a non-profit educational organization created in 2006 by educator Salman Khan with the aim of providing a free, world-class education for anyone, anywhere. The organization produces short lectures in the form of YouTube videos. In addition to micro lectures, the organization's website features practice exercises and tools for educators. All resources are available for free to anyone around the world. The main language of the website is English, but the content is also available in other languages.

In late 2004, Khan began tutoring his cousin Nadia who needed help with math using Yahoo!'s Doodle notepad.When other relatives and friends sought similar help, he decided that it would be more practical to distribute the tutorials on YouTube. The videos' popularity and the testimonials of appreciative students prompted Khan to quit his job in finance as a hedge fund analyst at Connective Capital Management in 2009, and focus on the tutorials (then released under the moniker "Khan Academy") full-time.

Contact process

The contact process is the current method of producing sulfuric acid in the high concentrations needed for industrial processes. Platinum used to be the catalyst for this reaction, however as it is susceptible to reacting with arsenic impurities in the sulfur feedstock, vanadium(V) oxide (V2O5) is now preferred.

This process was patented in 1831 by British vinegar merchant Peregrine Phillips. In addition to being a far more economical process for producing concentrated sulfuric acid than the previous lead chamber process, the contact process also produces sulfur trioxide and oleum.

If you go for too long without blinking, the emulsion falls apart - oil and water don't like to mix - and your cornea could become exposed to air. At best that's uncomfortable - at worst, the chronic deterioration of the tear film could lead to a condition known as "dry eye" or, more technically, keratoconjunctivitis s...

Sulfuric acid (H2SO4) is a strong, heavy acid with a
density of 1.84 g/cc and a marked tendency to
absorb moisture from the air, generating much heat.
Concentrated sulfuric acid (93-98%) is used in the
manufacture of fertilizers, explosives, dyes, and
petroleum products. Sulfuric acid is formed during the
Contact Process. The ContactProcess forms sulfur
trioxide (SO3) gas from sulfur dioxide (SO2) and oxygen
in a catalyst tower, and sulfuric acid is formed
when water is added. A mixture of H2SO4 and free
SO3 is equivalent to a sulfuric acid concentration of
over 100 percent. This mixture is called fuming sulfuric
acid or oleum.

Merkel contacts Social Democrat leader about forming coalition, but talks to wait for several days

Germany's ChancellorAngela Merkel said she has made the first contact with the head of the Social Democratic Party about forming a grand coalition government, but that any talks will have to wait for several days.
The Social Democrats are scheduled to hold a party convention on Friday, and will likely discuss participation in the government there.
Merkel's Union bloc scored its best result in 23 years on Sunday to put her on course for a third term, winning 41.5 percent of the vote and finishing only five seats short of an absolute majority in the lower house.
She now faces the delicate work of forming a coalition government.
Merkel's coalition partner, the pro-business Free Democrats, lost all their seats in Parliament after a much-criticised performance in Merkel's outgoing government.
Merkel and top party officials met on Monday to talk strategy about reaching out to the centre-left rivals they need to form a government.
She looks likely to end up leading either a "grand coalition" government with the centre-left Social Democrats of defeated challenger Peer Steinbrueck - reviving the alliance that ran Germany in her first term - or, less likely, with the environmentalist Greens.
Several weeks of difficult negotiations are expected, as both of the potential partners are likely to be wary of entering a coalition with the Christian Democratic Union (CDU).
Junior partners in the last two coalitions suffered disastrous defeats after four years of partnership with the CDU.

Contact mechanics is the study of the deformation of solids that touch each other at one or more points. The physical and mathematical formulation of the subject is built upon the mechanics of materials and continuum mechanics and focuses on computations involving elastic, viscoelastic, and plastic bodies in static or dynamic contact. Central aspects in contact mechanics are the pressures and adhesion acting perpendicular to the contacting bodies' surfaces (known as the normal direction) and the frictional stresses acting tangentially between the surfaces. This page focuses mainly on the normal direction, i.e. on frictionless contact mechanics. Frictional contact mechanics is discussed separately.
Contact mechanics is foundational to the field of mechanical engineering; it provides necessary information for the safe and energy efficient design of technical systems and for the study of tribology and indentation hardness. Principles of contacts mechanics can be applied in areas such as locomotive wheel-rail contact, coupling devices, braking systems, tires, bearings, combustion engines, mechanical linkages, gasket seals, metalworking, metal forming, ultrasonic welding, electrical contacts, and many others. Current challenges faced in the field may include stress analysis of contact and coupling members and the influence of lubrication and material design on friction and wear. Applications of contact mechanics further extend into the micro- and nanotechnological realm.

Learn how to use Microsoft Outlook to create contact groups so that you can send emails to a large number of people easily.
It is always better to create contact groups in outlook as it allows you to send emails to a large number of people easily. By creating groups you do not have to specify each and every email address specifically but can simply enter the contact group that consists of all email ids.
To understand how to do this, follow the tutorial below.
Step # 1 -- Select the "New Contact Group" icon
In outlook 2010 the "distribution list" is renamed to "contact group". This is the list that you will use to send out emails with Outlook to your contacts. It is easy to create contact groups once you have created the contacts. You will start by clicking the "contacts icon" in the "navigation pane". Then click on the "new contact group icon" at the top.
Step # 2 -- Enter the name
A new window will open the first thing you will do is to give the group a name, in this example "office staff". Once you have named the group, you would find it in your contacts. To make it appear right at the top, change the name by double clicking the group and in the name bar adding an "Underscore sign" before the name.
Step # 3 -- Add members
After you create contact groups in Outlook add contacts to it by double clicking on it and clicking on the "add members" icon. It will show you options from where you can add members to the group. In this example we will add members from the "outlook contacts". Once you select it, a window will appear showing you all the members. Add them by double clicking on the contact. After selecting the members click "ok" and a list of the selected members comes on the screen. From there, click "save and close".
You can at any point in time add a new member to the group or delete one by selecting it and clicking the "remove member" icon. Click "save and close" after you make changes.
Step # 4 -- Send email to group
There are four ways in which you can send emails in Outlook to a group. The first one is by right clicking on the group, going to "create" and selecting "E-mail". You will notice that the group name comes in the "To" line automatically. The second way to send an email is by opening the group, going to the communicate panel and clicking on the "E-mail icon". Another way to send an email is by going to the "folder list". The advantage of "folder list" is that you can see your contacts and mail box at the same time and drag the group in the inbox folder. The fourth and last way to send the email is simple you just have to click the "new Email" icon. A new email window will open. In the "To" bar type the first few letters of the contact.

They function to protect epithelial cells from infection, dehydration, and physical or chemical injury, as well as to aid the passage of materials through a tract."

Contact mechanics

Contact mechanics is the study of the deformation of solids that touch each other at one or more points. The physical and mathematical formulation of the subject is built upon the mechanics of materials and continuum mechanics and focuses on computations involving elastic, viscoelastic, and plastic bodies in static or dynamic contact. Central aspects in contact mechanics are the pressures and adhesion acting perpendicular to the contacting bodies' surfaces (known as the normal direction) and the frictional stresses acting tangentially between the surfaces. This page focuses mainly on the normal direction, i.e. on frictionless contact mechanics. Frictional contact mechanics is discussed separately.

About this Webinar!
Contact analysis is often nonlinear as the contact zone could change with applied loads, altering the boundary conditions on the various components of an assembly. Additionally, components made of highly flexible materials like elastomers could experience self-contact affecting their behavior and performance, requiring robust and efficient contact algorithms for simulations. Understanding how the contact detection works in FEA solutions helps users create better models and achieve accurate results. This presentation reviews the various methods available for contact analysis, along with the setup of a contact model. An overview of the methods of node-to-segment contact and segment-to-segment co...

Contact mechanics is foundational to the field of mechanical engineering; it provides necessary information for the safe and energy efficient design of technical systems and for the study of tribology and indentation hardness. Principles of contacts mechanics can be applied in areas such as locomotive wheel-rail contact, coupling devices, braking systems, tires, bearings, combustion engines, mechanical linkages, gasket seals, metalworking, metal forming, ultrasonic welding, electrical contacts, and many others. Current challenges faced in the field may include stress analysis of contact and coupling members and the influence of lubrication and material design on friction and wear. Applications of contact mechanics further extend into the micro- and nanotechnological realm.

About this Webinar!
Contact analysis is often nonlinear as the contact zone could change with applied loads, altering the boundary conditions on the various components of an assembly. Additionally, components made of highly flexible materials like elastomers could experience self-contact affecting their behavior and performance, requiring robust and efficient contact algorithms for simulations. Understanding how the contact detection works in FEA solutions helps users create better models and achieve accurate results. This presentation reviews the various methods available for contact analysis, along with the setup of a contact model. An overview of the methods of node-to-segment contact and segment-to-segment contact is also provided, so that users can choose the appropriate methods for simulations.

Manufacture Of Sulphuric Acid By Contact Process

Follow us at: https://plus.google.com/+tutorvista/
Check us out at http://chemistry.tutorvista.com/inorganic-chemistry/acids-bases-and-salts.htmlSulfuric acid
Sulfuric acid (H2SO4) is a strong, heavy acid with a
density of 1.84 g/cc and a marked tendency to
absorb moisture from the air, generating much heat.
Concentrated sulfuric acid (93-98%) is used in the
manufacture of fertilizers, explosives, dyes, and
petroleum products. Sulfuric acid is formed during the
Contact Process. The ContactProcess forms sulfur
trioxide (SO3) gas from sulfur dioxide (SO2) and oxygen
in a catalyst tower, and sulfuric acid is formed
when water is added. A mixture of H2SO4 and free
SO3 is equivalent to a sulfuric acid concentration of
over 100 percent. This mixture is called fuming sulfuric
acid or oleum.

Merkel contacts Social Democrat leader about forming coalition, but talks to wait for several days

Germany's ChancellorAngela Merkel said she has made the first contact with the head of the Social Democratic Party about forming a grand coalition government, but that any talks will have to wait for several days.
The Social Democrats are scheduled to hold a party convention on Friday, and will likely discuss participation in the government there.
Merkel's Union bloc scored its best result in 23 years on Sunday to put her on course for a third term, winning 41.5 percent of the vote and finishing only five seats short of an absolute majority in the lower house.
She now faces the delicate work of forming a coalition government.
Merkel's coalition partner, the pro-business Free Democrats, lost all their seats in Parliament after a much-criticised performance in Merkel's outgoing government.
Merkel and top party officials met on Monday to talk strategy about reaching out to the centre-left rivals they need to form a government.
She looks likely to end up leading either a "grand coalition" government with the centre-left Social Democrats of defeated challenger Peer Steinbrueck - reviving the alliance that ran Germany in her first term - or, less likely, with the environmentalist Greens.
Several weeks of difficult negotiations are expected, as both of the potential partners are likely to be wary of entering a coalition with the Christian Democratic Union (CDU).
Junior partners in the last two coalitions suffered disastrous defeats after four years of partnership with the CDU.

How to create contact groups in Outlook

Learn how to use Microsoft Outlook to create contact groups so that you can send emails to a large number of people easily.
It is always better to create contact groups in outlook as it allows you to send emails to a large number of people easily. By creating groups you do not have to specify each and every email address specifically but can simply enter the contact group that consists of all email ids.
To understand how to do this, follow the tutorial below.
Step # 1 -- Select the "New Contact Group" icon
In outlook 2010 the "distribution list" is renamed to "contact group". This is the list that you will use to send out emails with Outlook to your contacts. It is easy to create contact groups once you have created the contacts. You will start by clicking the "contacts icon" in the "navigation pane". Then click on the "new contact group icon" at the top.
Step # 2 -- Enter the name
A new window will open the first thing you will do is to give the group a name, in this example "office staff". Once you have named the group, you would find it in your contacts. To make it appear right at the top, change the name by double clicking the group and in the name bar adding an "Underscore sign" before the name.
Step # 3 -- Add members
After you create contact groups in Outlook add contacts to it by double clicking on it and clicking on the "add members" icon. It will show you options from where you can add members to the group. In this example we will add members from the "outlook contacts". Once you select it, a window will appear showing you all the members. Add them by double clicking on the contact. After selecting the members click "ok" and a list of the selected members comes on the screen. From there, click "save and close".
You can at any point in time add a new member to the group or delete one by selecting it and clicking the "remove member" icon. Click "save and close" after you make changes.
Step # 4 -- Send email to group
There are four ways in which you can send emails in Outlook to a group. The first one is by right clicking on the group, going to "create" and selecting "E-mail". You will notice that the group name comes in the "To" line automatically. The second way to send an email is by opening the group, going to the communicate panel and clicking on the "E-mail icon". Another way to send an email is by going to the "folder list". The advantage of "folder list" is that you can see your contacts and mail box at the same time and drag the group in the inbox folder. The fourth and last way to send the email is simple you just have to click the "new Email" icon. A new email window will open. In the "To" bar type the first few letters of the contact.

"Blinking also helps the oily meibum and water tears mix together to form an emulsion called tear film. If you go for too long without blinking, the emulsion falls apart - oil and water don't like to mix - and your cornea could become exposed to air. At best that's uncomfortable - at worst, the chronic deterioration of the tear film could lead to a condition known as "dry eye" or, more technically, keratoconjunctivitis sicca."

They function to protect epithelial cells from infection, dehydration, and physical or chemical injury, as well as to aid the passage of materials through a tract."
